My 2001 VW Polo has an electrical fault so my central locking doesn't work on the driver's side. It looks as if the cental locking is now failing on the passenger side as well. My worry is that I will be unable to unlock the petrol cap to fill up with fuel if the central locking fails completely on both sides of the car and I cant afford to get the problem repaired immediately.

Does anybody know if there is a way to manually unlock the petrol cap if the central locking isn't working? At least then I would be able to manage until I can get the problem sorted.

Thanks.
